new and useful Improvements in Stop Mech-= anlsm, of whlch the-"following is a SPGClfiCI tion, reference being had to the accompanying drawings. 4

I This invention relates to certain improvements in stop mechanism;'and the object of the invention is to provide a novel andim proved devlce Of'tlllS general character incombination with a rotary brush adapted to be rotated under the influence of a motor and whereby the rotation of such brush under the influence of the motor may be readily and conveniently controlled.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby-certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as willbe hereinafter more fully set forth. V

'The novel features'of the invention will be carefully defined inthe appended claims. 7 In order that my invention maybe the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein I Figure 1 is atop plan view, with apart in section, of a stop mechanism constructed in accordance with an embodiment of my invention;

Fig. 1 in close proximity to a side thereof;

and

Fig. 3 is a fragmentary side elevational view, illust-rating certain details of construction as herein embodied.

As disclosed in the accompanying drawings, 1 denotes a base of any ordinary or preferred construction having suitably secured theretofa casing 2 of any-desired configurationa-nd'Jincluding a hinged cover 3 whereby-access may be had within the casing, said hinged cover being also provided with a suitable opening or aperture 1 through which a peripheral portion of the cleaning brush 5 is adapted to be projected. 7 As herein disclosed, the brush 5 is carried by a shaft 6 removably supported within the side plates 7 of the casing 2 whereby Specification of team Patent. e m 12 1 27, 1917, seriaiivo. 835,206

such brush may be readily rcmoved or applied into operative position. As herein disclosed, the extremities of the shaft 6 are dircctedthrough the elongated open slots 8 produoed in the side plates-7 and such'extremities of the'shaft are operatively engaged by "the inverted hook members 9 pivotally securedto'the-inner faces of the side plates 7 whereby it will be readily perceived that such shaft 6 is effectively maintained in operative position under normal conditions. The shaft 6 has suitably aflixed thereto a pinion 10 in mesh with a large gear 11 carried by a second transverse shaft 12 operatively supported by the side plates 7. The shaft 12 is adapted to be rotated under the influence of the gear train 15 and the operating spring 16. A further detail of the mounting of the gear train 15 and the ooaction therewith of the spring 16 is believed to be unnecessa'ryas the same is substantially the same as a conventional clock mechanism.

The gear 11 has projecting laterally from one face thereof the equidistantly spaced pins 17 adapted to'beengaged by the weighted roclrarm 18 carried by the shaft 1 1, one extremity 19 of the shaft being projected exteriorly of the ca'sing 2 and being provided with the finger piece or rock arm 20 whereby it will be readily perceived that the shaft 1% may be so rocked as to elevate the rock arm 18 out of the path of travel of the pin 17 whereby the gear 11 will be permitted to rotate under the influence of the spring 16 to impart rotation to the brush 5'. The weight of the rock arm 18 will cause the same to automatically intersect the line of travel of the pins 17 when pressure on the finger piece or rock arm 20 is released whereby it will be readily observed that the brush 5 will be caused to rotate only during the interval it takes the pin 17 next adjacent to the pin released to engage the weighted ;arm 18,

While any means may be employed for limiting the movementJof-the-rock arm 18, I find it of advantage to provide the side plates 7 adjacent the finger piece or rock arm 20 with the outwardly directed projection 21 with which such key will abut.

From the foregoing description, it is thought to be obvious that a stop mechanism constructed in accordance with my invention is ofan extremely simple and comparatively inexpensive nature and is part culai'ly. wellfjadztpted for use by reason of the]ceflYenincejand' ability withwhich it may be as'sfennhlexil and by reesbrii'ofg-the efe, fe'ct'iVeneSSwith;Whiehit performs its funcii i an i w l a1so* bv1o ;th my'im "modificat oni withdlit material depaftu're fah'geme ntgend' jformation 0f: theiiseverel 'partsfhei ein shown gihearrying out inn iqnfi 'prectice except a s defi edby the f 1;; A; eviqe efitj e ehar'ztcteif desjc rihed in i cluding, a casing,;e shaft operatively eup- 'orted by "the casing; aggea'r train opera? arm' ar iflbYith i asti me Shaft ng l able? with the V projeetipnsg a sec'lid rock :arm
